Appuntamenti .my 1s. 1899.

To @ZZ whom t magazin/Germ Be it known that I, 'ARTHUR "R.- BULLooK', a citizen of the United States of America, and a resident of Cleveland, inthe county of Cuyahoga and State of` Ohio, have invented certain new and useful Improvements in Gras- Pressure-Reducing. Apparatus, of which the following is a specification. i v

kThis invention relates to contrivances for controllingr the gas pressure or pressures'between gas-generators and the points or places of or for consumption of gas; and the object of myinvention is to provide'an apparatus wherein and whereby a predetermined pressure may be maintained for or at thetermi nals of consumption of `gas regardless of Vliuctuations in the supply of gasto the'pressureregulator as well as an irregular consumption of gas therefrom. I attain this object in and by an apparatus constructed and equipped substantially in themanner as shown in the accompanying drawings, inwhichl Figure 1 is a central verticalsectional view of a pressure-regulator; and Fig. 2 is a horizontal sectional view of the same, taken on the line :r of Fig. 1.

Like letters of reference denote like parts in the drawings and specification.

The vessel A constitutes the chief element of the apparatus, being preferably Vof a cy lindrical form and of greater depth than width. Said vesselis provided at a'suitable point intermediate its top and bottom with a horizontally-extending diaphragm a', provided with a central opening of a size correspondingwith the diameter of a tube Inde-v pending from the under side of .said dia; phragm, said tube having open ends, as

shown, thereby providing a point of communication between the `space above and below said diaphragm. I.

From or through the top c of the vesselA extends vertically a` flue e, having its top provided with ya contracted opening or outlet f, its lower end being open throughout its diameter. As shown, said flue preferably extends to a point below the bottom of the tube b. The flue eis secured relatively to the vessel in any suitable manner.

is provided by the fiue e, 'this compartment 'and the lower compartment Z being in commu'nication through the open end of the said flue.

c designates an opening below the diaphragm a through the walls of the vessel and `forming'a means for connecting the lower compartment with a gas-generating apparatus. Y

h designates an opening or vent formed in the top c'of the vessel, said vent permitting the upper compartment to be subject to the atmospheric pressure.

Each of the several compartments is intended to receive suitable liquid, such as water, and preferably the level thereof is at a point in each compartmentwhere the compartment willbe filled to practically one-half its capacity, and thereby providing pressure-chambers in the compartment l and flue Ae, respectively, under the control of the -gas landa chamber viii-thevv upper compartment subject to the atmospheric pressure.'

Inprovidinga communicating port between the chamber in the'lower compartment and that within 'the flue e for thel passage of the gas,l 4which-is of an extremely-sensitive na- ]t'ure and which will' be effective, is the lnain feature ofthe present invention, inasmuch vas upon such port or passage-way depends the yefficiency of the pressure-regulator. This po'rt is preferably formed or provided as fol- :lows: v .l

Within the lower compartment lislocated jan annular float E, carrying one end of a pipe F,lthe 'end preferably exten'ding'above :the upper surface of the float, said pipe hav- ,ing its other end carried inwardly and up- `wardly within the iue e and terminating in a downwardly-extending portion, the Whole being of S form, both ends of the pipe being open. The bends of the pipe are arranged so as to permit of a verticall movement of the iioat E. Located in the upper compartment IOO `is a float C, carrying arms which extend downwardly and inwardlyinto the ue @and adapted to support a cup D, which is located within the ue c and movable vertically therein correspondingly with the movement of the oat C. The said cup D is adapted to contain liquid, and the free inner end of the pipe F extends therein, as shown. None of these parts necessarily come in Contact, and hence there is no liability ot the parts becoming useless through wear, duc.

It will now be understood that with a gasinlet at 'L' and a gas-outlet atfany increase of pressure in the chamber of the lower compartment will force the liquid in the vessel to rise in the upper compartment, while the water-level in the lower compartment will be lowered. This movement aects both floats, the float C rising, carrying with it the cup D, while the tloatE is lowered, lowering the end of the pipe F within the cup D, with the result that the liquid column at the end of the pipe F is increased in height and increasing the resistance to the passage ot the gas. As soon as the pressure in the chamber at the top of the iiue eis decreased (such pressure being primarily the canse of the movement just described) the height of the column of liquid in such ue is permitted to rise, lowr ering the level ofthe liquid in the upper compartment, and thereby permitting the cup D to descend and decreasing the resistance at the end of the pipe F, which in turn relieves the pressure in the lower compartment, causing the float E to rise and raising the pipe F and further decreasing the resistance at the outlet end 0f the pipe F. It will therefore be obvious that a liquid-check is formed at the end of the pipe F, the pressure of which is automatically controlled by the movements of the Iioats C and E, the latter having their movements by reason of the differences in pressure between the chambers in the lower compartment and the ue e, and the movements of the pipe F and cup D being in opposing directions it will be understood that the said check is exceedingly sensitive in character' and" of a form to be reliable in operation.

increased liquid-check, and vice versa, the construction is simple and efficient in operation and durable in structure.

m designates `a pipe located in the pipe F, said pipe m having its upper end above the upper end of the pipe F to permit, if desired, the attachment of a suitable pipe inserted through the opening t', by means of which a siphoning action can be had with the interior of the regulator.

It will be understood that a simple and eficient regulator extremely sensitive in its action and free from tendencies which would cause the parts to become worn is provided and one which is especially applicable to the control ot the passage of acetylene gas to the burners.

As an increase of pressure in the inlet end of the pipe F is counteracted by an Having thus described my invention, what I claim as new is- 1. A liquid-controlled gas-pressure-reducing apparatus comprising a vessel having a diaphragm with a depending tube; a iiue extending through said tube and communicating with the lower compartment; floats in the compartments formed by said diaphragm; and a gas passageway leading from the lower compartment to the said flue, said passageway having its outlet subjected to liquid-pres sure controlled by the movement of said floats.

2. A liquid-controlled gas-pressure-reducing apparatus comprising a vessel having a diaphragm with a depending tube; a fine eX- tending through said tube and communicating with the lower compartment; float-s in the compartments formed by said diaphragm; a. gas passage-way carried by the lower oat and leading from the lower compartment to the said tine; and means carried by the upper [ioat for subjecting the outlet end of said passage-way to liquid-pressure, the latter being regulated by the relative movement of the fioats.

3. A liquid-controlled gas-pressure-reducing apparatus comprising a vessel having a diaphragm with a depending tube; a flue extending through said tube and communicating with the lower compartment; iioats in the compartments formed by said diaphragm; and a sectional gas passage-way connecting said lower compartment and the line, the sections being carried by the said fioats, said passage-way having a variable liquid-resistance controlled by the movements of said fioats.

4. A liquid-controlled gas-pressure1'educ ing apparatus comprising a vessel having a diaphragm with depending tube; a fine extending through said tube; tloats in the compartments formed by said diaphragm; a cup within said flue carried by the upper Heat; and a pipe suspended by the lower tloat, the said pipe or conduit having one terminal in open relation with the gas-containing portion ot' said vessel and another terminal under a seal of liquid within said cup, substantially as described.

5. A hydrostaticallycontrolled gas-pressurereducing apparatus comprising a vessel, a diaphragm with depending tube in the lower portion of said vessel,a flue extending through said tube, a liquid-filled cup carried by a medium tloating above said diaphragm, and a pipe supported by a medium floating below said diaphragm, the said pipe extending from the gas-supply chamber into said cup, substantially as described.
